第五讲 篇章结构题a(2015宿迁市三模)depression can be a devastating illness，plaguing millions of people worldwide with feelings of sadness，hopelessness，and fatigue.despite numerous antidepressant drugs，as many as a third of patients dont respond to medication.this has forced doctors to be more creative in finding different treatments for the condition.in the past two decades，researchers have tied depression to a seemingly unrelated condition：inflammation(炎症)，the bodys natural response to stress.it could rise from injury or inflection，or even emotional issues like an unhappy marriage or problems at work.some amount of inflammation is generally beneficial，as it increases production of cytokines (致癌因子)，proteins that help us heal and protect us from the effects of overwork.but excessive cytokine levels，and the inflammation they bring on，could come at a cost.a number of studies suggest that high levels of cytokines could contribute to depression.cytokines can reach the brain several ways：directly through the bloodbrain barrier or indirectly by binding to nerve fibers elsewhere，which send signals to the brain to produce the inflammation molecules.in the brain，cytokines can disturb the production and release of several important signaling chemicals，including serotonin，dopamine and glutamate，which help control emotion，appetite，sleep，learning and memory.its thought that a lack of serotonin activity in the brain causes depression; most antidepressants increase the activity.but cytokines also have been shown to activate stress hormone signaling in the brain，which can also serve to develop depression.with all the evidence implicating inflammation in depression，doctors have been anxious to test antiinflammatory drugs as a potential treatment.four small students published between 2006 and 2012 by research groups in europe and iran found that adults diagnosed with depression who took aspirin or another antiinflammatory drug called c elecoxib，along with an antidepressant，got more relief from feelings of sadness，hopelessness，guilt and fatigue compared with those taking an antidepressant alone.however，andrew miller，a professor of psychiatry at emory university，thought something was amiss in these small，limited studies.none of them looked at whether the participants had to have high levels of cytokines before into the trap of viewing inflammatory drugs.“unfortunately，much of the field has fallen into the trap of viewing inflammation as the beall，endall，” miller says.he and his colleagues wanted to see whether the effect of these drugs was limited to the depression patients with high cytokine levels，or if it helped all people diagnosed with depression.【解题导语】这是一篇医疗文章阅读。文章主要介绍了抑郁症形成的过程和原因，也提供了一些治疗方法，但到目前为止还没有非常满意的疗效。1which of the following illustrates how depression is

ecosystem.unlike other animals，the african elephant is to a great extent the builder of its environment.as a giant planteater，it significantly shapes the forestandsavanna surroundings in which it lives，therefore deciding the conditions of existence for millions of other animals that live in its habitat.it is the elephants great desire for food that makes it both a disturber of the environment and an important builder of its habitat.in its continuous search for the 300 pounds of plants it must have every day，it kills small trees and bushes，as well as pulls branches off big trees.this results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the african savannas.in these open spaces，there are numerous plants in various stages of growth，which attract a variety of other planteaters.take the rain forests for example.in their natural states，the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.by pulling down trees and eating plants，elephants create open spaces，allowing new plants to grow on the forest floor.in such situations，the forests become suitable for largehoofed planteaters to move around and for smallsized planteaters to obtain their food as well.scientists are worried now that the african elephant has become an endangered species.if the elephant dies out，scientists say，many other animals will also disappear from vast areas of forests and savannas，greatly changing and worsening the whole ecosystem.【解题导语】本文是一篇说明文，文章主要介绍了非洲象对非洲大草原生态系统的巨大影响。5it can be

not the best player on the team，but most days you gave it your all.do you deserve a trophy(奖杯)?if the decision is up to carol dweck，the answer would likely be no.shes a psychology professor at stanford university，california.she says a player doesnt have to be the best to get a trophy.but those who receive an award should have to work for it.she suggests trophies go to the most improved player，or the one who contributed most to the team spirit，as well as to those who play the best.“the trophy has to stand for something，”dweck told tfk.“if we give a trophy to everyone，then the award has no value.”dweck argues that giving kids trophies for particular reasons，such as improving in a sport，teaches kids that adults value hard work and trying our best.others say that theres no harm in giving awards to all kids who play a sport，regardless of how they played or whether or not they improved.“i think we should encourage kids participation in sports，” says kenneth barish，a psychology professor at weill cornell medical college，in new york city.“a trophy is one way to encourage kids efforts.”barish argues that when we single_out only the best or even the most improved players with a trophy，we are teaching kids the wrong lesson.we are sending the message that winning is everything.“winning is only part of the equation(等式)，” barish told tfk.“playing sports also teaches kids about teamwork and the importance of exercise.”there will be plenty of opportunity for kids to learn about competition as they get older，says barish.theyll soon realize that only one soccer team wins the world cup and only one football team wins the super bowl.for now，he thinks theres nothing wrong with letting all kids who play a sport feel like winners.that means trophies for everyone.【解题导语】如果孩子参加体育比赛，那么是不是每个人都该得到奖杯呢？文章就这个问题给出了两种不同的看法。9according to carol dweck，which player should receive a trophy?atony，the most attractive player of
